OpenSAML user discussion

["Tom Scavo" <>]

I'm implementing a new SAML V1.1 statement type, a straightforward
extension of saml:SubjectStatementAbstractType:

<complexType name="SubjectStatementType">
 <complexContent>
   <extension base="saml:SubjectStatementAbstractType"/>
 </complexContent>
</complexType>

For example:

<saml:SubjectStatement
 xmlns:saml="urn:oasis:names:tc:SAML:1.0:assertion"
 xmlns:samlsap="someURI"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
 xsi:type="samlsap:SubjectStatementType">
 <saml:Subject>...</saml:Subject>
</saml:SubjectStatement>

The implementation extends SAMLSubjectStatement from OpenSAML V1.1.
So far I've been unable to obtain the required root element using the
method:

protected Element buildRoot(Document doc, boolean xmlns) {
   Element s = doc.createElementNS(XML.SAML_NS, "SubjectStatement");
   if (xmlns) {
       s.setAttributeNS(XML.XMLNS_NS, "xmlns", XML.SAML_NS);
       s.setAttributeNS(XML.XMLNS_NS, "xmlns:xsd", XML.XSD_NS);
       s.setAttributeNS(XML.XMLNS_NS, "xmlns:xsi", XML.XSI_NS);
   }
   s.setAttributeNS(XML.XMLNS_NS, "xmlns:samlsap", SAMLSAP_NS);
   s.setAttributeNS(XML.XSI_NS, "xsi:type", XSI_TYPE);
   return s;
}

This produces

<SubjectStatement
 xsi:type="samlsap:SubjectStatementType">
 <Subject>
   <NameIdentifier
     Format="urn:oasis:names:tc:SAML:1.1:nameid-format:X509SubjectName">
     uid=By-Tor,ou=tobes,dc=hades,dc=com
   </NameIdentifier>
 </Subject>
</SubjectStatement>

which is missing a namespace attribute (xmlns:samlsap).  If someone
could tell me what I'm doing wrong, I'd really appreciate it.

Thanks,
Tom
